Teflon suit

A type of material, invisible to the naked human eye, that grants the wearer immunity to all forms of duty and responsibility. Commonly found in bureaucratic fields of work, such as city government, state, and federal positions. Any request for work or assistance made towards the wearer of a teflon suit will instantly bounce off, rebounding to the nearest individual not in possession of a teflon suit.

"Hey, did you ask Gary for that bi-weekly report due today?"

"Yeah, I went to his desk to get it, but somehow I ended up on the other side of the building asking Rick for it."

"Sounds like Gary just got his teflon suit back from the dry cleaners."
